I'm just starting out as a NeXT programmer, so please forgive me if I'm
missing something obvious.

I'd like to use the NXReadTypes & NXWriteTypes functions to temporarily store
some instance variables in memory.  I looked in NeXT Concepts and the
NeXTStep Reference to come up with the idea of opening a memory stream,
converting that to a typed stream, and passing that to my object.

This is great except that you have to open a stream NX_READONLY or
NX_WRITEONLY.  I can't figure out how to do both.  I want to write to a
stream, then come back a while later and read the values back.

How can I read & write a stream?

Thanks in advance,
James
